  • “Hot” Gold: 24Kt satin-bright deposit that is stress-free, fine-grained, and extremely ductile. This deposit has exceptional corrosion and heatresistance, and has exceptional solderability, even after prolonged storage.
  • Purple Gold: 23.9Kt which co-deposits with metallic hardeners for added durability. Achieves a relatively low-stress deposit, is 99.7% pure, and results in a contact resistance of 4-7 mΩ.
  • Hard Gold: Durable deposit is excellent for connector pins and shells that will see multiple mating cycles and need to withstand sheering forces. The resulting deposit has a lower coefficient of friction than any of the other grades.
